Registering as a Part Author is straightforward, and so long as I am awake and connected, requests are dealt with quickly. You just need to read the Contributor Agreement and confirm that you agree by sending an email containing the words "I accept the LDraw.org Contributor Agreement with regards to all past and future contributions I make to LDraw.org" to parts@ldraw.org, and include your true name and LDraw forum ID.

Regarding this "part", it should really be submitted as three files
11125.dat - the frame
11140.dat - the wheel
u9081.dat - the tyre (unless someone knows the true design ID for this)
